ROOM TEMPERATURE CONTROLLER    GRC-1100

 
ROOM TEMPERATURE CONTROLLER (GRC-1100)

"GRC" Proportional Room Temperature Controller is intended to use to control
room temperature steadily.
Operating Voltage : AC 24V
Heating and Cooling exchanging function
Built-in temperature transmitter method ( Pt1000 )

This unit is designed for P-control.
Based on the differences between detected temperature and pre-set value,
This controller gives out put control signal is within 0~10V DC
When control signal varies, it varies from 0 to 100%
A variable is to control signal by means of mutual-proportion relation.

"GRC" model should be protected from the direct rays of the sun and other heat sources,
and located very well to detect the air temperature.
"GRC" can be installed in the Conduit Box and/or on the side wall directly by screw bolting.
Select a location approx 1.5 meter above the floor for "GRC" room temperature controller.
Avoid a location where air is not circulated well.
